ABSTRACT
Mineral deposits including metallic and non-metallic types occur in the Precambrian basement rocks of the Oban-Obudu area of southeastern Nigeria. This paper reviews the occurrence of metallic minerals in the area. These minerals include Iron and ferroalloy metals: manganese and ilmenite; non-ferrous and minor metals and related mineral deposits: tin, columbite and tantalite (Sn-Ta-Nb), monazite and precious metal: gold. These minerals are hosted in the metamorphosed basement rocks and intrusive pegmatites. The ages of these host rocks have been determined and correlated with the metallic mineral occurrences, hence defining the metallogeny of the Oban-Obudu area.
